Fig. 7: UV/Vis/NIR reflectance spectra of a reference cinnabar sample and unknown red paint samples from the Enkleistra. The identification of cinnabar in the red paints was possible due to the characteristic absorption edge (or band edge) of sulfur (S) and by pXRF spectroscopy with the photon emissions at 9.987 keV (L-alpha edge energy) and 11.823 keV (L-beta edge energy) characteristic of mercury.
